Question

1. Express 5m per second as a speed in kilometres per hour.​

Answer 1

Hello!

5m = 0.005km

1s = 1/3600h

0.005km/(1/3600h)

= (3600(0.005km))/(3600(1/3600h))

= 18km/h

Answer 2

To convert m/s to km/h, we need to multiply by a conversion factor of 3.6.

So, 5m/s = 5 x 3.6 = 18 km/h.

Therefore, the speed of 5m per second is 18km per hour.
